Thank you and thank the 'continuum' for your response.   I am somewhat familiar with the vmx file.    You are right that a VMTools install should not edit the vmx file.   But I do not see any method other than a manual edit to make the change.    And now that Microsoft is making the vmci file mandatory there should be an option somewhere other than to manually edit the file.   As I stated previously adding the vmci driver and not reviewing 'guest isolation' has the potential to lead to security issues.

Thank you and the 'continuum' for pointing me to the solution to this issue.
